Abstract

Optimum designs of 2-span continuous I-girder bridges are carried out. This design mainly aims to reduce the bridge weight. The global solution is figured out by beam theory approach; then, the design is optimized by FEM from the global solution. The design method is based on LRFD, and the design applies the newly developed material “SBHS”. The optimum calculation shows drastic reduction of steel weight.
